Description

本発明は、車体構造に関する。 The present invention relates to vehicle body structures.

例えば、ハイブリッド車などの電気モータを駆動源として走行する車両は、電気モータに電気を供給する蓄電装置が搭載されている。蓄電装置は、例えば、リヤシート（以下、シートという）における車両の後方に搭載され、ケースの内部にバッテリが収納されている。
ここで、例えば、シートの後方には荷室パンが設けられ、荷室パンの上方には荷室ボードが配置されている。荷室パンは、荷室ボードに対して下方に凹むように形成されている。荷室パンと荷室ボードとの間に収納空間が形成され、収納空間に蓄電装置が収納されている。 For example, a vehicle such as a hybrid vehicle that runs using an electric motor as a drive source is equipped with a power storage device that supplies electricity to the electric motor. A power storage device is mounted, for example, on a rear seat (hereinafter referred to as a seat) behind a vehicle, and a battery is housed inside a case.
Here, for example, a luggage compartment pan is provided behind the seat, and a luggage compartment board is arranged above the luggage compartment pan. The luggage compartment pan is formed so as to be recessed downward with respect to the luggage compartment board. A storage space is formed between the luggage compartment pan and the luggage compartment board, and the power storage device is stored in the storage space.

さらに、荷室ボードの前端部とフロアパネルとの間に隙間が形成され、この隙間は仕切部材で仕切られている。このため、例えば、車室側の物品などが隙間を経て収納空間に落ちることを仕切部材で防止できる（例えば、特許文献１参照）。 Furthermore, a gap is formed between the front end portion of the luggage compartment board and the floor panel, and this gap is partitioned by a partition member. Therefore, for example, the partition member can prevent articles and the like from falling into the storage space through the gap (see Patent Document 1, for example).

国際公開第２０１６／１２５３８８号WO2016/125388

しかし、特許文献１の構成では、荷室ボードの前端部とフロアパネルとの間の空間を仕切るために、仕切部材を別途設ける必要がある。そのことが部品点数を抑える妨げになっていた。
また、荷室ボードの前端部とフロアパネルとの間を仕切るために、仕切部材を配置するための余分なスペースを確保する必要があり、この観点から改良の余地が残されていた。 However, in the configuration of Patent Document 1, it is necessary to separately provide a partition member in order to partition the space between the front end portion of the luggage compartment board and the floor panel. This has hindered the reduction in the number of parts.
In addition, in order to partition the front end of the luggage compartment board and the floor panel, it is necessary to secure an extra space for arranging the partition member, and from this point of view, there is still room for improvement.

本発明は、部品点数の増やすことなく、かつ、余分なスペースを確保することなく、蓄電装置を収納する収納空間を車室から仕切ることができる車体構造を提供することを目的とする。 SUMMARY OF THE INVENTION An object of the present invention is to provide a vehicle body structure capable of partitioning a storage space for storing a power storage device from a passenger compartment without increasing the number of parts and securing extra space.

前記課題を解決するために、本発明は以下の手段を提案している。
（１）本発明に係る車体構造は、車両（例えば、実施形態の車両１０）の座席（例えば、実施形態のシート１５）に対して前記車両の後方に形成される凹部（例えば、実施形態の荷室パン１８）に配置される蓄電装置（例えば、実施形態の蓄電装置２０）と、前記蓄電装置の上面（例えば、実施形態の上案内部８７）から前記車両の前方かつ下方に向かって延在する案内部材（例えば、実施形態の案内部材６４）と、前記蓄電装置の蓄電素子（例えば、実施形態の電池セル４７）を冷却する空気を取り込む吸気部（例えば、実施形態の吸気部４１）と、前記蓄電素子と熱交換した空気を排出する排気部（例えば、実施形態の第３排気部４４）と、を備え、前記車両のフロア（例えば、実施形態のフロアパネル１４）を覆うカーペット（例えば、実施形態のカーペット１７）が、前記案内部材の上方まで延在されており、前記排気部は、前記案内部材における前記車両の後方に設けられ、前記車両の前方に向かって開口されている。 In order to solve the above problems, the present invention proposes the following means.
(1) A vehicle body structure according to the present invention is a recess (e.g., a recess in the embodiment) formed behind a seat (e.g., the seat 15 in the embodiment) of a vehicle (e.g., the vehicle 10 in the embodiment). A power storage device (for example, the power storage device 20 of the embodiment) arranged in the luggage compartment pan 18) and an upper surface of the power storage device (for example, the upper guide portion 87 of the embodiment) extending forward and downward of the vehicle. an existing guide member (for example, the guide member 64 of the embodiment) and an air intake section (for example, the air intake section 41 of the embodiment) that takes in air for cooling the power storage element of the power storage device (for example, the battery cell 47 of the embodiment). and an exhaust unit (for example, the third exhaust unit 44 in the embodiment) for discharging air heat-exchanged with the storage element, and a carpet (for example, the floor panel 14 in the embodiment) covering the floor of the vehicle ( For example, the carpet 17) of the embodiment extends above the guide member, and the exhaust section is provided behind the vehicle in the guide member and opens toward the front of the vehicle. .

この構成では、蓄電装置の上面から前方かつ下方に向かって案内部材を延在した。案内部材は、座席の後方に位置する。この案内部材の前方から案内部材の上方までカーペットを車室側から延在した。カーペットは車両のフロアを覆うように敷かれている。
このため、例えば、座席のシートバック（背凭れ）を前方側に傾倒した状態で座席を沈み込ませる、いわゆる座席をダイブダウンさせた状態において、座席と蓄電装置との間の隙間を塞ぐことができる。これにより、部品点数の増やすことなく、かつ、余分なスペースを確保することなく、蓄電装置を配置（収納）する凹部の収納空間を車室からカーペットで仕切ることができる。したがって、従来のような仕切部材を設けることなく、凹部に物が落ちることを防止できる。
さらに、例えば、蓄電装置から流出した空気が車室に流れ込むことを抑制できる。加えて、蓄電装置から発生した熱が車室に伝わることを抑制できる。
また、排気部を前方に向かって開口させ、この排気部を案内部材の後方に設けた。案内部材の上方にはカーペットが車室側から延在されている。このため、排気部の前方にカーペットが配置されている。これにより、温度の高い排気風が車室（客室）に直接流れ込まないようでき、乗員の空調快適性の悪化を抑制できる。 In this configuration, the guide member extends forward and downward from the upper surface of the power storage device. The guide member is positioned behind the seat. The carpet extends from the front side of the guide member to above the guide member from the passenger compartment side. Carpet is laid to cover the floor of the vehicle.
For this reason, for example, when the seat is sunk with the seatback (backrest) of the seat tilted forward, that is, when the seat is in a so-called dive-down state, the gap between the seat and the power storage device can be blocked. can. As a result, the storage space of the recess for disposing (storing) the power storage device can be separated from the passenger compartment by the carpet without increasing the number of parts and securing extra space. Therefore, it is possible to prevent objects from falling into the recess without providing a conventional partition member.
Furthermore, for example, it is possible to suppress the air that has flowed out from the power storage device from flowing into the vehicle compartment. In addition, it is possible to suppress the heat generated from the power storage device from being transferred to the vehicle interior.
Also, the exhaust portion is opened forward and provided behind the guide member. A carpet extends from the cabin side above the guide member. For this reason, a carpet is placed in front of the exhaust section. As a result, high-temperature exhaust air is prevented from flowing directly into the passenger compartment (passenger compartment), and deterioration of air-conditioning comfort for the occupants can be suppressed.

（２）前記蓄電装置の上面（例えば、実施形態のカバー６１）の側に位置するサービスプラグを備え、前記サービスプラグにおける前記車両の前方には、前記案内部材の車幅方向側方に設けられて、前記蓄電装置の上方に配置されるトランクボード（例えば、実施形態の荷室ボード１６）を支持する支持部材（例えば、実施形態の支持部材３７）が配置されていてもよい。 ( 2 ) A service plug is provided on the side of the upper surface (for example, the cover 61 of the embodiment) of the power storage device, and the service plug is provided on the vehicle width direction side of the guide member in front of the vehicle. A support member (for example, the support member 37 of the embodiment) may be arranged to support a trunk board (for example, the luggage compartment board 16 of the embodiment) arranged above the power storage device.

この構成では、トランクボードを支持する支持部材を、案内部材の車幅方向側方に設けた。案内部材の車幅方向側方に支持部材を連ならせることにより、温度の高い排気風を車室に一層流れ込み難くでき、乗員の空調快適性を一層高めることができる。
また、支持部材をサービスプラグの前方に設けた。このため、案内部材を、蓄電装置の車幅方向全域に延ばして、案内部材でサービスプラグを覆う必要がない。これにより、例えば、保守点検などの際に、サービスプラグに容易にアクセスできる。 In this configuration, the support member for supporting the trunk board is provided on the side of the guide member in the vehicle width direction. By arranging the support member on the side of the guide member in the vehicle width direction, it is possible to make it more difficult for the high-temperature exhaust air to flow into the passenger compartment, thereby further enhancing the air-conditioning comfort of the occupants.
Also, a support member is provided in front of the service plug. Therefore, it is not necessary to extend the guide member over the entire vehicle width direction of the power storage device to cover the service plug with the guide member. This allows easy access to the service plug, for example for maintenance.

（３）前記蓄電素子を収容し、上面（例えば、実施形態の上面３２ａ）が開口する収容部（例えば、実施形態の収容部３２）と、前記上面を覆うカバー部（例えば、実施形態のカバー部３６）と、を備え、前記カバー部は、排気ダクトと接続する排気ダクト接続部を有し、前記排気ダクト接続部は、前記カバー部の車両前方側に形成され、前記案内部材は、前記カバー部の上面に固定されるとともに、前記車両の上方視および前記車両の正面視で前記排気ダクト接続部と重ねられていてもよい。 ( 3 ) An accommodating portion (eg, the accommodating portion 32 of the embodiment) that accommodates the storage element and has an open top surface (eg, the top surface 32a of the embodiment), and a cover portion that covers the top surface (eg, the cover of the embodiment) 36), wherein the cover portion has an exhaust duct connection portion connected to an exhaust duct, the exhaust duct connection portion is formed on the vehicle front side of the cover portion, and the guide member includes the It may be fixed to the upper surface of the cover portion and overlapped with the exhaust duct connection portion when viewed from above the vehicle and when viewed from the front of the vehicle.

この構成では、案内部材をカバー部の上面に固定し、車両上方視、および車両正面視において排気ダクト接続部に案内部材を重ねた（オーバーラップさせた）。このため、車両上方視および車両正面視において、排気ダクト接続部を案内部材で覆うことができる。これにより、例えば、座席のシートバック（背もたれ）を前方側に傾倒した状態で座席を沈み込ませる、いわゆる座席をダイブダウンさせた状態において、排気ダクト接続部を乗員から目視できないように隠すことができる。
また、案内部材も車室側から延在するカーペットで覆われているので、車室の美観（外観）を向上できる。 In this configuration, the guide member is fixed to the upper surface of the cover portion, and the guide member overlaps (overlaps) the exhaust duct connection portion when viewed from the top of the vehicle and from the front of the vehicle. Therefore, the connecting portion of the exhaust duct can be covered with the guide member when viewed from the top of the vehicle and from the front of the vehicle. As a result, for example, when the seat is sunk with the seat back (backrest) tilted forward, in a so-called dive-down state, the exhaust duct connection can be hidden from the occupants' eyes. can.
In addition, since the guide member is also covered with the carpet extending from the passenger compartment side, the beauty (appearance) of the passenger compartment can be improved.

本発明によれば、部品点数の増やすことなく、かつ、余分なスペースを確保することなく、蓄電装置を収納する収納空間を車室から仕切ることができる。 ADVANTAGE OF THE INVENTION According to this invention, the storage space which accommodates an electrical storage apparatus can be partitioned off from a vehicle interior, without increasing a number of parts and ensuring an extra space.

Further, the third exhaust portion 44 is provided behind the guide member 64 and the support member 37 (see FIG. 9), for example, and opens forward.

図１に示すように、蓄電装置２０は、左支持ブラケット８１および右支持ブラケット８２により、左リヤフレーム８３および右リヤフレーム８４(双方図１０に示す)に支持されている。この状態において、蓄電装置２０は、荷室パン１８の収納空間２９（図１１参照）に配置されている。 As shown in FIG. 1, power storage device 20 is supported by left rear frame 83 and right rear frame 84 (both shown in FIG. 10) by left support bracket 81 and right support bracket 82, respectively. In this state, power storage device 20 is arranged in storage space 29 (see FIG. 11) of luggage compartment pan 18 .

図１、図３、図４に示すように、蓄電装置２０は、送風ファン３４を駆動することにより、車室２２（図１参照）の空気を吸気部４１に矢印Ａの如く取り込む。取り込んだ空気をバッテリモジュール３３に導き、バッテリモジュール３３（すなわち、電池セル４７）と熱交換する。バッテリモジュール３３を熱交換により冷却した空気は、第１排気部４２、第２排気部４３、および第３排気部４４（図６も参照）に導かれる。 As shown in FIGS. 1, 3, and 4, the power storage device 20 drives the blower fan 34 to draw air from the passenger compartment 22 (see FIG. 1) into the air intake portion 41 as indicated by an arrow A. As shown in FIGS. The taken air is led to the battery module 33 and heat-exchanges with the battery module 33 (that is, the battery cells 47). The air that cools the battery module 33 by heat exchange is guided to the first exhaust section 42, the second exhaust section 43, and the third exhaust section 44 (see also FIG. 6).

第１排気部４２に導かれた空気は、第１排気部４２を経て第１排気ダクト７３（図８参照）に矢印Ｂの如く導かれる。第１排気ダクト７３に導かれた空気は、左サイドフレーム１２のうち、前述した排気ダクトの一部を経て車室２２に矢印Ｃの如く排出される。

図３、図７、図８に示すように、案内部材６４は、板金でダクトカバー６２を覆うように形成されている。板金製の案内部材６４で樹脂製のダクトカバー６２を覆うことにより、ダクトカバー６２を案内部材６４で保護できる。
案内部材６４は、上案内部８７と、前案内部８８と、を有する。上案内部８７は、ダクトカバー６２の上面６２ａを覆うように概ね水平に配置された状態において、例えばカバー６１の上面（カバー部３６の上面）に固定されている。前案内部８８は、ダクトカバー６２の前面６２ｂを覆うように、上案内部８７（すなわち、蓄電装置２０の上面）の前辺から前方で、かつ、下方に向かって延在されている（図１１も参照）。これにより、案内部材６４は、車両上方視および車両正面視において、第１排気部４２、第１排気ダクト７３、および第２排気部４３にオーバーラップされた状態に重ねられている。 As shown in FIGS. 3, 7, and 8, the guide member 64 is formed so as to cover the duct cover 62 with sheet metal. By covering the duct cover 62 made of resin with the guide member 64 made of sheet metal, the duct cover 62 can be protected by the guide member 64 .
The guide member 64 has an upper guide portion 87 and a front guide portion 88 . The upper guide portion 87 is fixed to, for example, the upper surface of the cover 61 (the upper surface of the cover portion 36) in a substantially horizontal arrangement so as to cover the upper surface 62a of the duct cover 62. As shown in FIG. The front guide portion 88 extends forward and downward from the front side of the upper guide portion 87 (that is, the upper surface of the power storage device 20) so as to cover the front surface 62b of the duct cover 62 (Fig. 11). Thus, the guide member 64 overlaps the first exhaust section 42, the first exhaust duct 73, and the second exhaust section 43 when viewed from above and from the front of the vehicle.

図９から図１１に示すように、案内部材６４の車幅方向側方に支持部材３７が設けられている。支持部材３７は、ＤＣ電源ケーブル７１を前方側から覆うように設けられ、さらに、プラグリッド６３およびサービスプラグ（図示せず）の前方に配置されている。
支持部材３７および案内部材６４は、蓄電装置２０の上方に配置される荷室ボード１６を支持する。ここで、支持部材３７および案内部材６４は、フロアパネル１４の後方に配置されている。フロアパネル１４（図１も参照）には、カーペット１７が敷かれている。カーペット１７は、前後方向において案内部材６４に対応する部位１７ａが、案内部材６４の前案内部８８を経て上案内部８７まで後方に延在されている。
なお、カーペット１７は、前後方向において案内部材６４に対応する部位１７ａに加えて、支持部材３７の前面部３７ａを経て上面部３７ｂまで後方に延在させてもよい。 As shown in FIGS. 9 to 11, a support member 37 is provided on the lateral side of the guide member 64 in the vehicle width direction. The support member 37 is provided so as to cover the DC power cable 71 from the front side, and is arranged in front of the plug grid 63 and the service plug (not shown).
Support member 37 and guide member 64 support luggage compartment board 16 arranged above power storage device 20 . Here, the support member 37 and the guide member 64 are arranged behind the floor panel 14 . A carpet 17 is laid on the floor panel 14 (see also FIG. 1). A portion 17 a of the carpet 17 corresponding to the guide member 64 in the front-rear direction extends rearward to the upper guide portion 87 via the front guide portion 88 of the guide member 64 .
The carpet 17 may extend rearward through the front surface portion 37a of the support member 37 to the upper surface portion 37b in addition to the portion 17a corresponding to the guide member 64 in the front-rear direction.

以上説明したように、実施形態の蓄電装置２０では、図７、図９、図１１に示すように、案内部材６４の上案内部８７がダクトカバー６２の上面６２ａを覆うように配置されている。さらに、案内部材６４の前案内部８８が上案内部８７の前辺から前方で、かつ、下方に向かって延在されている。加えて、案内部材６４は、シート１５の後方に位置する。この案内部材６４の前方から案内部材６４の上方までカーペット１７が車室２２側から延在されている。カーペット１７はフロアパネル１４（図１参照）を覆うように敷かれている。 As described above, in the power storage device 20 of the embodiment, the upper guide portion 87 of the guide member 64 is arranged to cover the upper surface 62a of the duct cover 62, as shown in FIGS. . Further, the front guide portion 88 of the guide member 64 extends forward and downward from the front side of the upper guide portion 87 . Additionally, the guide member 64 is positioned behind the seat 15 . The carpet 17 extends from the front side of the guide member 64 to above the guide member 64 from the compartment 22 side. A carpet 17 is laid to cover the floor panel 14 (see FIG. 1).

このため、例えば、シート１５をダイブダウンさせて、荷室ボード１６の前ボード１６ａをめくりあげた状態において、シート１５のシートバック２３と蓄電装置２０の案内部材６４との間の隙間をカーペット１７で塞ぐことができる。
また、例えば、カーペット１７を支持部材３７の前面部３７ａを経て上面部３７ｂまで後方に延在させてもよい。この場合にも、荷室ボード１６の前ボード１６ａをめくりあげた状態において、シート１５のシートバック２３と蓄電装置２０の支持部材３７との間の隙間をカーペット１７で塞ぐことができる。 For this reason, for example, when the seat 15 is dived down and the front board 16 a of the luggage compartment board 16 is turned up, the gap between the seat back 23 of the seat 15 and the guide member 64 of the power storage device 20 is covered with the carpet 17 . can be blocked with
Further, for example, the carpet 17 may extend rearward through the front surface portion 37a of the support member 37 to the upper surface portion 37b. In this case as well, the gap between the seat back 23 of the seat 15 and the support member 37 of the power storage device 20 can be covered with the carpet 17 when the front board 16a of the luggage compartment board 16 is turned up.

これにより、部品点数の増やすことなく、かつ、余分なスペースを確保することなく、蓄電装置２０を配置（収納）する荷室パン１８の収納空間２９を車室２２からカーペット１７で仕切ることができる。したがって、従来のような仕切部材を設けることなく、荷室パン１８に物が落ちることを防止できる。 As a result, the storage space 29 of the luggage compartment pan 18 in which the power storage device 20 is arranged (stored) can be separated from the passenger compartment 22 by the carpet 17 without increasing the number of parts and securing extra space. . Therefore, it is possible to prevent objects from falling into the luggage compartment pan 18 without providing a conventional partition member.

また、図３、図６、図９に示すように、第３排気部４４が前方に向かって開口されている。第３排気部４４は、案内部材６４や支持部材３７の後方に設けられている。さらに、案内部材６４の上方にはカーペット１７が車室２２側から延在されている。また、支持部材３７の上方にもカーペット１７を車室２２側から延在させてもよい。
このため、第３排気部４４の前方にはカーペット１７が配置されている。これにより、温度の高い排気風が車室２２に直接流れ込まないようでき、乗員の空調快適性の悪化を抑制できる。加えて、蓄電装置２０から発生した熱が車室２２に伝わることを抑制できる。 Further, as shown in FIGS. 3, 6, and 9, the third exhaust portion 44 is open forward. The third exhaust section 44 is provided behind the guide member 64 and the support member 37 . Furthermore, the carpet 17 extends from the compartment 22 side above the guide member 64 . Further, the carpet 17 may be extended from the passenger compartment 22 side above the support member 37 as well.
Therefore, the carpet 17 is arranged in front of the third exhaust section 44 . As a result, high-temperature exhaust air can be prevented from flowing directly into the passenger compartment 22, and deterioration of air-conditioning comfort for the occupant can be suppressed. In addition, the heat generated from power storage device 20 can be suppressed from being transferred to vehicle interior 22 .

さらに、図９、図１０に示すように、荷室ボード１６を支持する支持部材３７が、案内部材６４の車幅方向側方に設けられている。案内部材６４の車幅方向側方に支持部材３７を連ならせることにより、温度の高い排気風を車室２２に一層流れ込み難くでき、乗員の空調快適性を一層高めることができる。
また、支持部材３７がプラグリッド６３の前方に設けられている。このため、案内部材６４を、蓄電装置２０の車幅方向全域に延ばして、案内部材６４でプラグリッド６３を覆う必要がない。これにより、例えば、保守点検などの際に、プラグリッド６３を外してサービスプラグ（図示せず）に容易にアクセスできる。 Further, as shown in FIGS. 9 and 10, a support member 37 that supports the luggage compartment board 16 is provided on the side of the guide member 64 in the vehicle width direction. By connecting the support member 37 to the lateral side of the guide member 64 in the vehicle width direction, it is possible to make it more difficult for the high-temperature exhaust air to flow into the passenger compartment 22, and to further improve the air-conditioning comfort of the occupants.
A support member 37 is provided in front of the plug grid 63 . Therefore, it is not necessary to extend the guide member 64 over the entire vehicle width direction of the power storage device 20 to cover the plug grid 63 with the guide member 64 . This allows easy access to a service plug (not shown) by removing the plug grid 63, for example, during maintenance and inspection.

加えて、図３、図７、図８に示すように、案内部材６４は、カバー部３６（具体的には、ダクトカバー６２およびカバー６１の一部）の上面に固定されている。さらに、案内部材６４は、車両上方視および車両正面視において、第１排気部４２にオーバーラップさせた状態に重ねられている。このため、車両上方視および車両正面視において、第１排気部４２を案内部材６４で覆うことができる。
これにより、例えば、シート１５をダイブダウンさせて、荷室ボード１６の前ボード１６ａをめくりあげた状態において、第１排気部４２を乗員から目視できないように隠すことができる。 In addition, as shown in FIGS. 3, 7, and 8, the guide member 64 is fixed to the upper surface of the cover portion 36 (specifically, the duct cover 62 and part of the cover 61). Further, the guide member 64 overlaps the first exhaust portion 42 when viewed from above and from the front of the vehicle. Therefore, the first exhaust portion 42 can be covered with the guide member 64 when the vehicle is viewed from above and when the vehicle is viewed from the front.
As a result, for example, when the seat 15 is dived down and the front board 16a of the luggage compartment board 16 is turned up, the first exhaust section 42 can be hidden from the eyes of the occupant.

また、図９に示すように、カーペット１７のうち案内部材６４に対応する部位１７ａが、案内部材６４の前案内部８８を経て上案内部８７まで後方に延在されている。これにより、カーペット１７の部位１７ａで案内部材６４が覆われ、車室２２の美観（外観）を向上できる。 9, the portion 17a of the carpet 17 corresponding to the guide member 64 extends rearward to the upper guide portion 87 via the front guide portion 88 of the guide member 64. As shown in FIG. As a result, the guide member 64 is covered with the portion 17a of the carpet 17, and the appearance (appearance) of the passenger compartment 22 can be improved.
